RIVERSIDE - A low-pressure storm system is expected to reach the Inland Empire on Tuesday, March 19, bringing light rain and a chance of thunderstorms, according to the National Weather Service.

The system is expected to move inland across Southern California tonight and could begin dropping rain late tonight, forecasters said.

Up to an inch of rain is expected in the Riverside metropolitan area and Lake Elsinore through Thursday night, while the San Gorgonio Pass near Banning could get around two-tenths of an inch and up to a half-inch is forecast for the Riverside County mountains, according to the NWS.

Less than one-tenth of an inch of rain is expected in the Coachella Valley.

Snow levels will fall to around 5,000 feet by late Wednesday night and remain there through Thursday night, forecasters said.

The storm will also bring a slight chance of thunderstorms Wednesday afternoon through early Wednesday evening.

It is unlikely that flooding, mud and debris flows will develop around the Cleveland National Forest and the Temescal Valley, according to the Riverside County Emergency Management Department.

A wide area skirting the eastern boundary of the Cleveland National Forest was left exposed to potential flood and mud damage because of the 23,000-acre Holy Fire in August. The arson blaze denuded steep terrain below Santiago Peak, permitting water to flow unchecked onto lower slopes where subdivisions are situated.

Heavy rainfall on Valentine's Day resulted in significant flooding, prompting street closures and evacuations. A homeless woman died Feb. 14 when she was swept away by a heavy water flow in a concrete stormwater channel in Riverside, and several homes in Lake Elsinore were damaged by the downpour.

The inclement weather is expected to leave the region by late Thursday night and make way for another low-pressure system set to reach Southern California on Saturday, forecasters said.
